A. initial stage (1973- 1979).
1973, American Amchem company developed styrene-butadiene latex which can be automatically deposited on iron-based surface, that is, 600 series automatic swimming paint, which is used for painting automobile frame structures such as automobile lampshades and axles. 1977, Amchem company was acquired by union carbide company, and the research and development of self-swimming paint stopped.
B. Improve the promotion stage (1980- 1999). 1980 henkel acquired Amchem company and resumed the research on various polymer applications. 198 1 developed acrylic 700 series self-swimming paint with high thermal stability (230℃), 1982 developed PVC resin 800 series self-swimming paint which can be baked and cured at 100℃ and contains no heavy metals, and can obtain high corrosion resistance. From 65438 to 0987, Henkel merged Amchem Company and Parker Company, which significantly strengthened its sales, R&D and technical service resources. By 1998, autophagy coating technology has been successfully applied in all continents except Antarctica.
C. innovation development stage (2000-present). In 2000, 900 series epoxy self-swimming paint was introduced into the market. In 2002, the 100 self-swimming paint coating production line was put into production, including four newly commercialized 900 series self-swimming paint coating production lines. Since then, Henkel has re-integrated R&D strength, increased investment and devoted itself to the research and development of a new generation of self-swimming coating technology. The latest light-colored series products based on epoxy 900 self-swimming paint have completed laboratory research and will be commercialized soon, marking the arrival of self-swimming paint farewell to the single black era. Compared with the traditional painting process, the self-swimming painting process has the advantages of less equipment investment, small required site area, simple process operation, environmental protection and energy saving, low operating cost and excellent corrosion resistance of the coating, and can be widely used in the painting of automobile parts. Henkel has more than 50 patents on autoswimming coating technology, and its global users exceed 130. Henkel also has technology research and development centers in North America, Europe and Japan, with an annual coating area of about 50 million M2. In North America, about 65% of automobile seats and 35% of automobile shock absorbers are painted by self-swimming painting technology. Black self-swimming paint has been successfully used to paint thousands of automobile parts. In the Asia-Pacific region, the latest 900 series self-swimming paint has been used to coat the bodies of construction machinery and agricultural machinery.
